Abstract

La présente invention concerne un noyau de segment et un moteur à flux axial. Le noyau de segment est formé en recouvrant un noyau SMC (100, 100') sur une surface périphérique externe d'un noyau stratifié (200, 200'). Une surface externe du noyau de segment, qui est difficile à traiter, est formée en traitant le noyau SMC facile à façonner (100, 100'). L'ensemble de la structure du noyau stratifié (200, 200') est relativement simple. Par conséquent, un moule de traitement du noyau stratifié (200, 200') nécessite des spécifications simples. De plus, le moule peut être utilisé pour effectuer facilement un traitement, ce qui réduit les difficultés du traitement du noyau de segment. Le noyau de segment présente des performances électromagnétiques supérieures à celles d'un noyau de segment n'utilisant qu'un matériau SMC. De plus, il présente un taux d'utilisation du noyau supérieur à celui d'un noyau de segment n'utilisant qu'un noyau stratifié (200, 200').
